Certain aspects of the disclosure provide techniques for random access channel (RACH) power control, including for message (MSGA) transmission by a user equipment (UE) for two-step RACH procedure. Certain aspects provide a method for wireless communication generally including determining a transmit power for transmitting a first message to a base station (BS) as part of a two-step RACH procedure, the first message comprising a first part and a second part. Determining the transmit power comprises determining a first transmit power for transmitting the first part based on a first function having parameters including a power ramping counter and a power ramping step. Determining the transmit power further comprises determining a second transmit power for transmitting the second part based on a second function having parameters including the power ramping counter and the power ramping step. The method further includes incrementing the power ramping counter based on transmitting the first message.
